Setting Fire to Chicago's Railway Lines to Keep them Running

 
  Carnot Minister for Railways

While here in Australia we have heat WOLOs and buckling lines, in Chicago the opposite is true in a big cold snap:

I assume this refers to point heaters which are standard in the UK. They were not too popular in the early days because manually keeping points clear was good money! They are just for keeping the moving blades and rods etc moving instead of icing up. I would guess propane or similar for the flames.

They are also common in North America. Can be seen along most northern transcontinental lines. They are gas fired, The gas tanks get topped up just before winter and I think operate automatically when needed.
Bit of a media beat-up really as they have been around for decades and have been quietly doing their bit for years without any media attention.

Interesting to see them in action though, apparently the UK is in for a big blast of cold in the next week or so after a relatively mild winter.

I agree.

Routine course of action in the USA and not newsworthy, but I would think that any pro-rail person on here would be quite appreciative of any media attention showing that rail is taking care of business rather than dismissive.

It's interesting to see the fires warming the tracks but do they ever worry about the sleepers catching fire?
